IMPROVEMENT IN MACHINES FOR CRIMPING HEEL-STIFFENERS FOR BOOTS ANDSHOES.

pec fication forming part of Letters Patent No. 213,191, dated March 11,1879; application filed August 30, 1878.

To all whom it may concern:

Be it known that I, ll/IERRITT H. HALL, of the city and county ofPhiladelphia, State of Pennsylvania, have invented new and usefulImprovements in Machinery for Dieing and Crimping Heel-Stiffenin gsforBoots and Shoes, and I hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawing, which is a front view of my invention, and lettersof reference marked thereon.

This invention relates to machinery for forming into proper shape thecounters or stifienings placed above the soles in boots and shoes andconsists of a movable male plunger, a female di in three parts, withlever-arms restin g on abutments of a movable bed-plate, which issupported by springs above a rigid bed-plate, to which are attached ahinged pair of crimping-jaws, operated by levers, cams, and springs, thewhole constituting a forming or molding and crimping device, which maybe placed and operated in an ordinary pressing-machine.

I will now proceed to more fully describe the construction and operationof this inventlon.

In the accompanying drawing, which forms a part of this specification,Ais a male plunger, attached to the movable platen B B, placed so itsvertical center line coincides with that of the female die 0 C and jointdevice D. This (lie rests upon its extremities G, which bear against theabutments E E of the movable bed-plate F, which are supported by thesprings O 0 above the rigid bed -plate H, which has a lug, K, to whichare hinged the two crimping-jaws L L, drawn open by the springs G Gagainst the closing-levers I I, which pivot on the posts P P, to whichare attached the springs M M, for opening the jaws of the female die bydrawingthemback against a stop-pin or shoulder. The bed-plate H alsocarries two posts, N N, which support the levers I I and prevent thecrimping-jaws L L from opening too far.

The joint device D at the bottom of the female die has a feather ortongue to prevent its being displaced, and provides a pivoting-surface,partially rotating around which the j aws of the die may open withoutshowing a crack into which the material of the stiffening might drop andprevent their closing. They are kept in close contact by springs of agum or elastic substance inserted in the abutments E E of the bed-plateF. J J are cam projections on the movable platen B B, which operate thelevers I I.

The method of operating thisinventionis as follows: All being in place,the stiffener, cut to proper shape, is placed with its longest edgefront in the space between the plunger and female die. The platen B isthen caused to descend, which, forcing the male plunger down, firmlyholds the stiffening by its center, and, continuing to descend, thefemale dies 0 O are forced against the abutments E E, which, resistingfurther motion, cause the con1- pression of the stiffening. Now thesprings 0 0 begin to yield and the bed-plate descends, allowing the camsJ J to operate the levers I I, by which the crimping-arms L L areclosed, thereby crimping the edge of the stiffening over the front faceof the plunger A.

I am aware that molding a stiffener to the shape required when in theshoe is not a new process, and that machines have been made for thispurpose, all of which I wish to distinctly disclaim 5 but What I doclaim as my invention, and wish to secure as such by Letters Patent, is-

1. The female die 0 (l, with joint device D, in combination with a maledie or former, constructed substantially as and for the purposehereinbefore set forth.

-2. The female die 0 O, with extended arms or extremities, incombination with the abutment E on bed-plate F and crimping-jaws, all

substantially as set forth.

3. The crimping-jaws L L, levers I I, and bed-plate H, in combinationwith cams J J, bed-plate B, plunger A, female die 0 G, and movablebed-plate F, when constructed substantially as and for the purposehereinbefore set forth and described.
